lnGreat Britain November's,

This invention relates to cigarettes and panic ecting' part oi th'e mouthpiece tube preferablyis effected by aidalmovemei t of the cigarette thereinto, suchaxlal' movementbeing effected by means adapted tocarry the cigarette into and through the'bore or chamber in which the mouthpiece is located so. that the mouthpiecels thereby ejected a'nd 'thefprojecting' part thereof at the "same time pressed around the cigarette.

The invention is hereinafterdescribed' by way of example with reference to the accompanying 1o diagrammatic drawings, in which: v

As illustrated in Figure 1 of the accompanying diagrammatic drawings a mouthpiece filling i is provided with an enclosing tube 2 having a projecting partZa at one end and a filter tip or like composite cigarette is produced by applying a cigarette 3 into such projecting part 20 of the mouthpiece. a

As shown in Figure 2 the mouthpiece may be formed by wrapping. around the filter tip 8 or other filling, a length 2b of paper, cork or other suitable material cut at 20 from a continuous strip thereof in such manner as to provide the projecting part 2d at one end of the tube. The strip material may be plain or may be provided with serrations 2d at the projecting edge or with for manufacturing the same. g a v 'According to the present invention, a filter tip or like composite cigarette is producedby applying together anordinary. cigarette, which may be of shorter length than normal and is preferably produced on the continuous rod. machine, and a mouthpiece comprising a filter tip orother desired mouthpiece filling enclosed in'a tube of paper and/or cork or other suitable material, such tube projecting at one end of the filter tip or mouthpiece filling for the reception of the adjacent end of the cigarette.

The projecting. part of thetube enclosing the mouthpiece filling may be formed with serrations, slits or the like to permit such part to be flared out in order to facilitate entry of the cigarette. Alternatively, the end of the cigarette may be tapered or otherwise constricted for the same purpose. The projecting part of the tube enclosing the mouthpiece filling may be previously coated internally with adhesive, such adhesive being moistened previous to the insertion of the cigarette. Alternatively, adhesive may be applied to the interior of the projecting part of the tube and/or to the cigarette prior to their association together. The mouthpiece filling may be enclosed in the tube by rolling a length of material around the same or by wrapping material around the filling while moving axially on the continuous rod principle. In either case the mouthpiece filling may be ofdouble length with the tube projecting at each end so as to provide two mouthpieces when the filling is bisected, and in such a case cigarettes may be applied to the opposite projecting ends of the tube prior to such bisection.

The invention furthermore includes apparatus for carrying out the aforesaid method comprising an intermittently movable carrier having bores or the equivalent for the reception of the mouthpieces, means for flaring out the projecting part of the tube and for applying adhesive or moisture rettesand to an improved method of and means the projecting part of the mouthpiece.

Alternatively, apparatus for carrying out the method specified may comprise an intermittently movable carrier having bores or chambers for the mouthpieces, means for tapering or otherwise constricting the end of the cigarette, and means for applying the cigarette into the projecting part of the mouthpiece tube.

The application of the cigarette into the proslits 26, as shown in Figure 5, so that, as indicated in Figures 4 and 7, the projecting part 2a may be flared outwardly to facilitate the entry of the cigarette 3 thereinto.

Alternatively, as illustrated in Figure 3, a continuous strip 222 of paper, cork or other desired material having mouthpiece fillings i applied thereon at suitably spaced intervals is cut off at suitable positions by means-ofauserrated cutter, therebyf ormng the serrations 2d, and the lengths 2b are wrapped around the mouthpiece fillings i, for instance, by means of a wrapping belt, rollers or the like while moving axially on the continuous rod principle. Similarly, as illustrated .in Figure 6, mouthpiece fillings l are applied on a continuous strip 217 at suitably spaced intervals and the strip 212 is formed into a tube enclosing the spaced fillings, such tube being subsequently cut off into lengths each containing a mouthpiece filling. The strip 2b of paper may be previously formed with longitudinally extending slits 26 as shown, so that the projecting part of the tube enclosing the filling will be capable of being flared out, as shown in Figure 7, to facilitate the entry of the cigarette 3.

In all cases the mouthpiece filling may be of double length, for instance, as illustrated in Figures 3 and 6, the mouthpiece tube being arranged to project at each end and the filling being bisected on the line 2f.

The paper strip from which the mouthpiece tubes are formed may be provided in any other suitable manner with slits, perforations, serrations or the like so that the projecting part of the tube of the mouthpiece produced will be provided with slits or serrations or be constituted by projections, flaps or the equivalent.

In one embodiment of apparatus (see Fig. 8) suitable for carrying out the method described, an intermittently movable drum 4 or other carrier having bores or equivalent chambers for the reception of the mouthpieces is arranged to receive the mouthpieces from the mouthpieceforming apparatus (not shown) a stop 4a being provided to position the mouthpieces in the bores or chambers. After insertion into the carrier 4, each mouthpiece is carried into alignment with a plunger 5 which is rotated and is caused to enter the projecting part of the mouthpiece tube, the plunger having a bevelled part So by which such projecting part 2a of the tube may be flared outwardly. The plunger 5 also may serve to apply adhesive or moisture, for instance, by the provision of a wick 6 or the like engaging the end of the plunger 5 when in its rearmost position and conveying adhesive or moisture thereto from a container 1. After the projecting part 2a of the mouthpiece has been flared and coated with adhesive or has had a previously applied coating of adhesive moistened in the manner described, it is brought by the carrier 4 into alignment with cigarette feeding means, for instance comprising co-operating feed rollers 9 by which cigarettes are fed successively from a guide 8 so as to be moved axially into the projecting part 2a of the mouthpiece tube 2, the cigarette being fed completely through the bore in the carrier 4 so as to effect the discharge of the mouthpiece, the flared part of the mouthpiece tube being closed around the cigarette during its passage through the aforesaid bore, and the final discharge of the completed cigarette being effected by a pair of co-operating feed rollers 9a.

In a modification as illustrated in Figure 9, the necessity for flaring the projecting part 2a of the mouthpiece tube 2 is avoided by tapering or otherwise constricting the end of the cigarette 3.

For example, as illustrated in Figure 10, cigarettes located in an intermittently movable carrier it, for instance a drum provided withbor'esor channels, are brought successivelylnto alignment'with amember W, which preferably is rotated, having a coned recess Illa in its end face whereby on engaging with the cigarette 3 the end of the cigarette is tapered or constricted, as indicated at 3a, the cigarette being positioned during this operation, for example by means of a stop I241. The cigarettes are then brought successlvely into alignment with co-operating feed rollers 9 and are ejected into engagement therewith, for instance, by a plunger H. The feed rollers 9 feed the cigarette 3 axially into the pro- Jecting part 2a of a mouthpiece tube 2 located in alignment in a chamber in an intermittently movable carrier 4 into which the mouthpieces have been inserted at a previous stage. The projecting parts of the mouthpieces are previously coated with adhesive or moistened for instance, by the provision of a rotatable plunger 5 cooperating with a wick 6 conveying adhesive or moisture from a container 1 and having a bevelled edge 51; to ensure its entry into the projecting part 2a of the mouthpiece tube, which latter is positioned during its operation, for example, by means of a stop 4a.

It will be understood that the invention is not limited to the particular embodiments hereinbefore described. For example, the projecting part of the mouthpiece tube may be pressed into engagement with the cigarette after insertion of the latter thereinto by means such as rollers, brushes or the equivalent. Double length mouthpiece fillings located at a middle position in tubes may be utilised, in which case cigarettes may be simultaneously applied to the opposite ends of the tube and the double mouthpiece thereafter bisected.

Furthermore, the mouthpiece tube may be.

ejected from a chamber in a drum or carrier into engagement with the end of a cigarette located in alignment with the mouthpiece and held, for instance, in a chamber in the same or in a similar drum or carrier. In this case pressing of the projecting part of the tube into engagement with the cigarette may be effected by reciprocating rollers, brushes or the like operating in suitable timed relation to the mouthpiece-ejecting means.

In a further arrangement the mouthpiece insertion and the cigarette may be moved towards one another in chambers in a drum or carrier or suitably associated drums or carriers, means such as rollers or brushes being. provided for pressing the projecting part of the tube around the end of the cigarette. If the projecting part of the mouthpiece tube is made suificiently long and of adequate strength, the use of adhesive for securing the cigarette in such projecting part may be dispensed with.

What I claim is:

1. A method of producing cigarettes having mouthpiece fillings, comprising applying mouthpiece fillers at spaced intervals on a strip of wrapping material, cutting said material into sections of a length greater than that of the filler, wrapping the flller to form a cylindrical mouthpiece having a tubular projecting portion, and securing one end of a length of cigarette rod insaid projecting portion.

2, A method of producing cigarettes having mouthpiece fillings, comprising applying mouthpiece fillers at spaced intervals on a strip of wrapping material, cutting said material into sections of a length greater than that of the filler, wrapping the filler to form a cylindrical mouthpiece having a tubular projecting portion extending beyond the filler at each end thereof, securing one end of a length of cigarette rod in each projecting portion, and cutting said mouthpiece intermediate its ends to form two cigarettes provided with mouthpiece fillings.

3. A method of producing cigarettes having mouthpiece fillings, comprising applying mouthpiece fillers at spaced intervals on a strip of wrapping material, cutting said material into sections of a length greater than that of the filler, wrapping the filler to form a cylindrical mouthpiece having a tubular projecting portion extending beyond the filler at each end thereof, cutting said mouthpiece intermediate its ends, and securing one end of a length of cigarette rod in the tubular projection provided on each half of the severed mouthpiece.
